Got it. Either the windows 7 compatibility mode or running as administrator fixed it. Thanks for the tip.

Spoke too soon. Tried turning back on some of the stuff that I'd turned off in BIOS. Guess its trial and error to see what's causing the issue. Also, how do you set Compatibility with Windows 7 when I'm already running windows 7? There is no Crossfire option to disable either... probably because I'm using a single card. Edit : Found the compatibility tab.

Well it suddenly decided to behave. Weird. Thanks for the suggestions. One of them must have worked. I'll be watching it suspiciously for a while.

Definitely no overclocks. Still running Windows 7 64 bit. Did a reinstall earlier, but I'll try again and launch as admin.

Any suggestion of other games that use similar graphics? I ran up Goat Simulator and Minecraft. No problems. [Hey, I'm scratching for stuff I can load on... and I don't want to download World of Tanks...]

Checked. None found.

Temp is within normal operating levels. 50 ish degrees. I ran a stress test on it that hiked it up much higher than that. [without incident] Same video card works fine in another computer with the game.

Having some problem getting NA to run properly on my kids PC. Core 2 due 8500. 8 gig Ram Currently a ATI 7700 video card, but also tried a ATI 6870, and a some other thing I had lying around that I forget. I've done a fresh install of windows 7. Updated video drivers, MB driver. Changed monitor and cable. Changed vid card twice. Cannot figure what is wrong. Other games play fine. diagnostics say vid card is fine. Its just NA that won't behave.
